What Stadtwerke Bruchsal does

Stadtwerke Bruchsal GmbH is a municipal multi-utility (Stadtwerke) wholly owned by the City of Bruchsal, Germany, founded in 1976 and celebrating its 50th anniversary in 2026. The company delivers electricity, natural gas, drinking water, district heating (Fernwärme), public city bus transport, and swimming facility operations to residential and commercial customers in Bruchsal and surrounding districts including Heidelsheim, Helmsheim, Ober- and Untergrombach, Büchenau, and (for some services) Stutensee. Core operations are exercised through the subsidiaries Energie- und Wasserversorgung Bruchsal GmbH (ewb) and Stadtbusverkehr Bruchsal GmbH, plus the SaSch! indoor/outdoor pool and sauna complex and two further outdoor pools (Heidelsheim and Obergrombach). The company also operates as the designated basic grid operator and default supplier within its network area and runs a Netzportal for digital network connection management.

Revenue is generated across ten interlocking streams: consumption-based residential and business electricity (COMFORT*Strom* max, BUSINESSStrom fix/ökoPlus/smart, WÄRMEStrom fix), gas (BUSINESSGas fix/öko fix with 10% biomethane, BUSINESSGas CO2-kompensiert), drinking water, geothermal-sourced district heating, network usage fees (Netzentgelte) and metering fees under MsbG, EV charging fees and THG quota trading, PV leasing (PV-Pachtmodell) and heat contracting for commercial customers, public bus fares under the Stadtbus 'max' brand, and admissions/courses at Bäderwelt (SaSch! and two Freibäder). Pricing is partially publicly disclosed (e.g., BUSINESSStrom fix at 38.65 ct/kWh plus €115.85/year service fee; water price raised by 10 Cent/m³ net effective 1 September 2025) and partially individualized for business customers and heat contracting. Distribution combines two physical service centers, a full self-serve online portal with tariff calculators, telephone sales, and direct B2B consultation for commercial customers.

The most consequential capital program is the 'SWB Strategie 2045', anchored by a 10-year exclusive geothermal heat supply contract with Geothermie-Gesellschaft Bruchsal signed January 2026 and a ~900-meter district heating pipeline to the western industrial area, with John Deere Werke Bruchsal as first industrial connection targeted for September/October 2026. The district heating renewable share is targeted at minimum 60% from launch, rising toward 100% by 2035. The strategy also includes a Windpark Bruchsal Nord development, a continued ~4,000-unit per-cycle smart meter rollout, thermal storage buffer installation, and adjacent municipal services contracts (e.g., Stutensee street lighting covering 3,454 lanterns). Certifications (TÜV Nord green power and biogas, OK Power, TÜV Rheinland CO2-compensated gas, GDPR-compliant data handling) and community sponsorship (Kultursommer, Theatersommer, school initiatives) underpin the company's positioning as the regional energy and quality-of-life provider for the Bruchsal conurbation.
